Hávamál (The Sayings of the High One) consists out of Old Norse poems from the Viking Age that present advice for living, proper conduct and wisdom.

The runes are of the Younger Futhark runic alphabet which was used during the Viking Age. "Grimfrost" is written in the Younger Futhark with a stung K-rune, turning it into a G-rune. Stung runes appeared during the Viking Age, around the year 1000.
